Transparent granule for PP and PE melt-flow adjustment
A transparent granule documented to increase PP melt-flow index and decrease PE melt-flow index, with resin-specific trial directions.
25 kg paper-poly pouch
TDS-derived technical profile
Key values listed for A-490
The following technical values are taken from the current TDS to support grade selection and initial formulation work.
| Property | Listed value | Condition |
|---|---|---|
| Density | 0.98 g/cm³ | — |
| MFI | ≥41,000 g/10 min | Source TDS value |
| Molecular weight | >120,000 | — |
| Ash | <0.05% | — |
| Moisture | <0.5% | — |
What this grade is positioned to support
- Increase PP melt-flow index
- Decrease PE melt-flow index
- Flow-window formulation trials
How to prepare the first evaluation
- 01
Define the base polymer and current/target MFI before dosing.
- 02
Blend A-490 for 5-8 minutes with virgin, recycled or outlet material.
- 03
Proceed by extrusion, injection molding or blow molding after uniform mixing.
